Divided and this application led December 28, 1930., Serial No. 504,718.

My invention belongs to that general class of devices known as heating apparatus, and relates more particularly to an improved radiator construction, or the like, for steam, hot water or other similar systems and is a division of my copending application, Serial No. 634,492, filed April 25, 1923 and allowed December 3, 1930,whieh has now matured into Patent No. 1,810,721, granted June 16, 1931.

The invention has among its ob'ects the production of an apparatus of the ind described that is simple, compact, attractive,

inexpensive, of light weight, economical and eiicient.

One of the principal objects of the invention is to provide a construction in which air flowing into the structure is positively caused to circulate through the device.

Another object of the invention is to provide a radiator having means for causing ail.' to flow in the above mentioned manner- Another object of the invention is to provide a stack having an opening at its upper portion and an opening at the lower portion thereof and having a radiator arranged at the lower opening, the radiator providing means for directing air `in an upwardly direction relatively to the stack.

It is another object of theinvention to provide a stack having a radiator disposed at the lower opening thereof in a manner to cause air entering the stack to be heated and be directed in an upwardly and rearwardly direction relatively to the interior of the stack.

ous embodiments of which the invention is Y susceptible, it being therefore obvious that other changes and modifications may be resorted to without departing from the spirit o the appended claims forming a part hereo In the drawin Fig. 1 is a front elevation p f a stack embo ying the features of invenf ion;

Fig. 2 is a section taken on the line 2-2 of Fig. 1 Fig. 3 1s a section taken on the line 3-3 of Fig. 1;

Fig. 4 is a construction Y Fig. 5 is a section taken on line 5--5 of Fig. 4; and

' Fig. 6 is a section taken on line 64-6 of front elevation of a modified The stack'generally designated 10 has an opening at the up er portion thereof and an opening 16 locate adjacent the lower end thereof. A radiator unit generally designated 17A is located ad'acent the lower opening and perforated sheives 18-18 are disposed within the interior of the stack above the radiator generall desi nated 17. A damper 19 is located wlthin t e interior of the stack to regulate the How of heated air from the stack which also provides a means :for regulating the iiow of air into the stack. The stack illustrated in Fig. 1 has an openin 20 whereby access to the shelves 18 may be ad. '2I`2his opening 20 is closed by the doors 21 and The radiator generally designated 17 includes headers 23 and 24, tubes V25 and heat radiating fins 26, it being understood that the tubes are arranged in spaced relation to each other as clearly shown in Fi 1 and that the heat radiating fins exten between the tubes and provide passages whereby air entering the opening 16 in the lowermost portion of the stack may Bow into the interior of the stack and be directed in an upwardly and rearwardly direction relatively to the interior of said stack. In the structure shown in Figs. 1 and 2, the radiator unit 17 is disposed dia onally within the interior of the stack andghas one end thereof located adjacent the upper extremity of the opening 16 and extends therefrom toward the rear portion of the stack or wall 14 which thus arranges the passages of the radiator at an incline in a manner to direct the incoming air in an upwardly and rearwardly direction relatively to the interior of the stack. A perforated shelf 27 may be arranged at the upper opening 15 of the stack.

It is manifestthat the structure just described provides a means whereby air may enter the interior of the stack, be heated and directed in a heated condition upwardly and rearwardly of the stack.

In the construction shown in Figs. 4 to 6, inclusive, a stack 28 is employed which has an opening 29 provided at the u per end thereof and an opening30located in t e lowermost portion thereof. A radiator or heat exchange unit 31 is arranged in a `vertical position across the opening 30. The radiator includes headers 32 and 33 and vertically extending tubes 34 and heat radiating fins 35, the latter of which are arranged at an obtuse angle to the tubes and thus rovide passa eways which will 'direct the a1r {lowing trough the radiator in an upwardly and also rearwardly direction. A damper 36 is provided to regulate the introduction and escape of air to and from the stack and a deflector 37 is located at the upper opening so as to deflect air laterally of the stack.

By the arrangement just described, it is evident that the passages formed by the ns which are located between the tubes such as 34 provide means for directing the air in an upwardly and rearwardly direction.

From the foregoing description, it is manifest that a simple and eflicient construction is provided whereby air to be heated may pass through the radiator or heat exchange unit, be heated thereby and directed into the stack in an upwardly direction relatively to the interior of the stack.

Having thus described the invention, what I claim and desire to cover by Letters Patent 1s:
